No-Cement Corundum Refractory Castables.
Novobilská, Martina ; Kovář,, Pavel (referee) ; Nevřivová, Lenka (advisor)
This thesis deals with the problem of no-cement corundum refractory castables. In the theoretical part, it focuses on NCC refractory and its use, production technology and input raw materials. The second part of the theoretical work deals with MgAl2O4 spinel. The practical part of the thesis then continues in the topic and focuses on cement-free refractory concrete and the influence of MgO content on their properties.

Analysis of advanced materials and structures by SIMS method
Holeňák, Radek ; Kalousek, Radek (referee) ; Bábor, Petr (advisor)
Bachelor theasis deals with the study of advanced materials by SIMS method and the possibilities of kvantitative analysis using maesured data. Chemical analysis of the ceramic surface in order to optimize the measurement conditions was performed. The rest of the work uses the data output from the measurement to describe the internal microstructure of the material. Using sophisticated methods, Si precipitates in the AlSi layer are localized and described, and the formation of the MgAl2O4 phase in ceramic samples is confirmed. Achieving all the set goals reveals the potential of the SIMS method and, above all, the possibility of processing the data output from the measurements.
